Potential Percussive Activities

The construction of the pedestrian bridge over Lake James has the potential to generate some
percussive activities in the form of pile driving. Construction of the two-end bends will require
the driving of 6 H-piles, 3 in each end bent. The driving of these piles would take approximately
2-3 days. Noise generated from the pile hammer could potentially impact nearby roosting
habitat of the Northern long-eared bat. There are multiple occurrence records for this species
within 15-miles of the project site; however, no known maternity roosts are located within 150-
feet of the project site and no known hibernacula sites are within ¼ mile of the project site;
therefore, a “not likely to adversely affect” determination is warranted for northern long-eared
bat (personnel communication with Bryan Tompkins, USFWS on 10-11-18).
